What the data measures
Estimated population at midyear, counting residents regardless of citizenship or legal status.
World Bank WDI brings together population estimates from UN population publications and national statistical sources. Estimates use censuses and demographic information on births, deaths, and migration.
Coverage & limitations
United States and Canada · 2000–2025 (available years vary by series)
- This is a midyear estimate rather than a census-day count.
- Population estimates can be revised when censuses or migration estimates change.
- Country-level figures do not describe local population growth. Preserve source footnotes, including preliminary estimates.
